…rms in vpa and vperp, for testing of the compatibility of the pseudospectral and the finite-element methods for advection and collisons, respectively. The option is chosen by selecting the [geometry] option = "0D-Spitzer-test", and picking fixed constant values of Ez, dBdr, Er, and dBdr. The vperp_advection!() routine must update the z_advect and r_advect structs if nr == 1 and nz == 1 and the "0D-Spitzer-test" option is being used, leading to some duplication of code. This could be avoided if the speed updates happened outside the function where the advection terms are computed.

PR to enable tests where vpa and vperp advection routines are used alongside collision operators.
Intended to provide fair tests of the pseudo-spectral and finite-element numerical methods and determine what boundary conditions are required for vperp advection, if any.
